How Do Xingke Portable Evaporative Coolers Work?

AS The temperature of the remaining water drops , water is evaporated by the moving air. Heat and energy is carried away by the faster moving molecules as water in the Air Cooler evaporates.when the water evaporates the air near the surface increases its relative humidity and would slow down the evaporation if it was not blown away and replaced with air with a low relative humidity. The wind from the Evaporative cooler fan increases evaporation and the rate the energy leaves the liquid water.


Temperatureis a measure of the energy in the water.Since the energy in the remaining water is dropping so too is the temperature of the remaining water. The same thing happens when you lick the back of your hand and blow on it. It feels cool. This is how an evaporative cooler works. Water is pumped over porous pads where air is drawn through causing the water to evaporate and cool the air.


The result is that hot dry air is converted into cool moist air that is blown into a house for cooling. The process works best when there is a good flow of air and the relative humidity of the incoming air is below 30%. The efficiency (cooling effectiveness) goes down with an increase in the relative humidity of outside hot air.


Experiment - Examining relative humidity effects on evaporative cooler operation

In many location where there is low relative humidity, one effective and inexpensive means to cool houses and businesses is with evaporative coolers. These use a fan to draw hot, dry outside air through water wetted pads where evaporation of the water cools the air. The cool moist air is then blown into the house and distributed for cooling.This experiment allows you to input the outside air relative humidity and the outside air temperature to obtain the temperature of the air that is blowing from the Air Cooler into the house.

What you find: For a given temperature of outside air, as the relative humidity rises the temperature drop between the outside and inside air becomes less and less. For very dry air or low relative humidity,the temperature drop can be 30 degrees or more. Temperatures greater than 80 degrees in the output air to the house is usually considered too high and few people will use them when this occurs.
